1 Claim. (Cl. 131-176) This application is a divisional application of now abandoned application Serial No. 421,412, filed April 6, 1954 for Smoking Pipes and Cigar and Cigarette Holders.

The present application embodies an invention relating to new useful improvements in covers for smoking pipes in which:

Figure 1 is a side elevation of my invention.

Figure 2 is a top plan view of same.

Figure 3 is an elevational view, showing in detail the top of the pipe bowl in Figure 1.

Figure 4 is a plan bottom view of the cover shown in Figure 1.

Figure 5 is a sectional view through the cover taken on line 55 in Figure 4; while Figure 6 is a sectional view thorugh the pipe bowl and cover taken on line 6-6 in Figure 2, with the lower portion of the bowl omitted.

Referring more particularly to the drawing, a cover as shown in Figure 1, and especially in Figure 4, is arranged at the top of a pipe bowl 25, a pin 26, protruding from the outer surface at the top of said bowl, is adapted to cooperate with an elongated bayonet slot 27 in the cover.

The outer edge of the top of the pipe bowl is provided with numerous recesses 29, see Figures 3 and 6, while the inside of a flange 31 of the cover is formed with depressions 30, as shown in Figures 4, 5 and 6.

Within the top of said cover is formed an annular shoulder 32, and between the flange 31 and this shoulder 32 is provided an annular channel 33 for the access of air into the center 36 of the cover from depressions 30 in the flange 31 by means of cut-away portions 34 made in said annular shoulder 32.

A space 35 is left between the cover and the pipe bowl to admit air to the pipe, when in use.

When the two passages 29 and 30, by movement of the pin 26 in the bayonet slot 27, are not in alignment, the flow of air into the bowl of the pipe would be shut oil.

In operation, when the cover device by adjustment of the pin 26 relative to the elongated bayonet slot 27, is set for draft-inlet to the pipe, air is drawn from the space 35 between the bowl of the pipe and the cover into the recesses 29 and depressions 30, when these are in register, and then into the channel 33 between the flange 31 of said cover and the shoulder 32, and from there through the cut-away portion 34 in the shoulder 32 into the center 36 of the cover.

We claim as our invention: 1

In a device of the class described, a pipe bowl formed with recesses at the top of its outer surface, a detachable cover mounted on saidbowl, a pin protruding from the outer side of said bowl, a flange upon the cover, the

inside of said flange having recesses adapted to register with the recesses of said bowl, and an annular shoulder formed within the cover and concentric with the flange of the latter and seating on the top of said bowl, said cover having a channel between the shoulder and said flange, the shoulder being formed with cut-away portions therethrough connecting the inner center of the cover with a channel; and saidcover having a bayonet slot adapted to cooperate with said pin, whereby, when in adjusted position, to convey air to the interior of the pipe bowl.
